In accordance with the provisions of the patent statute, I havedescribed my invention, but I desire it understood that it is notconfined to the particular form shown and described, the same beingmerely illustrative, and that the invention can be carried out in otherways without departing from the spirit of my invention, and therefore, Iclaim broadly the right to employ all equivalent instrumentalitiescoming within the scope of the appended claims, and bymeans of which,objects of my invention are attained and new results accomplished, as itis obvious that the particular embodiments herein shown and describedare only some of many that can be employed to attain these objects andaccomplish these results.

Having now described my invention, what I claim and desire to secure byLetters Patent, is:

1. In an electrolytic condenser the combination with a cathode containerof a plurality of flat anode discs, superimposed in such fashion thatthey are alternately inclined toward each other at opposite angles tofacilitate the disengagement of air bubbles, due to electrolytic action.

2. An electrolytic upright condenser having a plurality of aperturedfiat anode plates, made of one continuous ribbon, bent and rebentalternately in such fashion that it forms a zigzag ascent ofsuperimp'osed'single plates, inclined toward each other and toward thevertical axis of the condenser, and an electrode pole, passing throughthe apertures of said plates and provided with means to secure theplates in proper position.

, 3. In an electrolytic condenser, in combination with a cathodecontainer and an electrolyte therein, an anode comprising a polesupported in an upright position and centrally located relative to thecontainer and a continuous strip of thin metal perforated at spacedintervals, said strip being bent in a sinuous curve and said pole beinginserted through said perforations to support the strip an means at theupper end of said pole to keep said strip under tension and below thelevel of the electrolyte.

4. In an electrolytic condenser in combination with a cathode containerand an electrolyte therein, an anode comprising a pole supported in anupright position and centrally located relative to the container and acontinuous strip of thin metal comprising disc portions and narrowconnecting portions and having perforations centrally located in saiddisc portions, said strip being bent in a sinuous curve and said polebeing inserted through said perforations to support said strip, andmeans at the upper end of said pole to keep said strip under tension andbelow the level of said electrolyte. v

5. In an electrolytic condenser, in combination with a cathode containerand an electrolyte therein, an anode comprising a pole supported in anupright position and centrally located relative to the container and acontinuous strip of thin metal comprising disc portions and narrowconnecting portions and having perforations centrally located in saiddisc portions, said strip being bent in a sinuous curve and said polebeing inserted through said perforations to support said strip with saiddisc portions transverse and said connecting portions parallel to thewall of the container, and means at the upper end of said pole to keepsaid strip under tension and below the,

level of the electrolyte.
